Description
Tailgate Hinge CB Antenna & Flag Mounting Bracket for Jeep Wrangler JL JLU 2018-2021
This dual-purpose tailgate hinge mount gives you a solid, no-drill mounting point for both a CB antenna AND an off-road flag on your 2018-2021 Jeep Wrangler JL or JLU. The two-in-one design eliminates the need for separate mounts and keeps both accessories securely attached through the roughest trails. The bracket sandwiches between the factory tailgate hinge and body — no drilling, no cutting, fully reversible. Ideal for overland rigs, trail convoys, and dune-running where a whip flag is required.
Key Features
-
Two-in-One Design: Separate mounting holes for a CB/ham antenna (3/8 inch x 24 thread) AND an off-road flag/whip (1/2 inch hole) — run both simultaneously from one bracket
-
No-Drill Installation: Mounts using the factory tailgate hinge bolts — simply remove the existing bolts, position the bracket, and reinstall with the included longer stainless hardware
-
Heavy-Duty Stainless Steel: 3/16 inch thick 304 stainless steel with black powder coat finish — won't rust, won't flex, built for years of trail abuse
-
Optimal Tailgate Location: Rear-corner mounting provides excellent ground plane for antenna performance and high visibility for off-road flags
-
Complete Hardware Kit: Includes bracket, all mounting bolts, washers, nylon lock nuts, antenna stud adapter, and detailed installation guide

Why This Mount?
When you're running dunes or leading a trail convoy, you need both communication and visibility. This bracket solves both needs from a single mounting point. The tailgate hinge location is one of the strongest structural points on the JL body, and the no-drill design preserves your Jeep's integrity. Plus, having the antenna at the rear corner maximizes ground plane — a key factor in CB radio performance that many fender mounts compromise.
Frequently Asked Questions
Q: Will this fit a 2019 JLU Sahara?
A: Yes, this mount fits all 2018-2021 Wrangler JL and JLU models regardless of trim level. The tailgate hinge bolt pattern is identical across the JL platform.
Q: Can I mount it on either side of the tailgate?
A: Yes, the bracket is designed to mount on either the driver or passenger side tailgate hinge. Most users prefer the passenger side to keep the antenna away from the fuel filler area.
Q: Does the antenna interfere with opening the tailgate?
A: The bracket moves with the tailgate when opened, so there's no interference. For very tall antennas (5+ feet), the antenna will swing with the tailgate — folding or quick-disconnect adapters are recommended for daily use.
Q: Can I use this with oversized tires on the tailgate?
A: The bracket mounts to the hinge, not the tailgate itself. It clears most tailgate-mounted spare tires up to 37 inches. For 40+ inch tires, verify clearance before ordering.
Q: Does this work with aftermarket tailgate reinforcement kits?
A: Most reinforcement kits that use the factory hinge bolts are compatible. If your reinforcement kit replaces the hinge bolts with its own hardware, you may need longer bolts (available at any hardware store) — contact us for bolt specs.
